Cation-Induced Pesticide Binding and Release by a Functionalized Calix[4]arene Molecular Host

Abstract

Ion-controlled switchable progress is very important in many biological behaviors. Here, we reported K+-controlled switch, this switch system exhibited excellent carbaryl (G) binding/release by fluorescent (FL), ultraviolet-visible (UV) spectrums and 1H NMR spectroscopy. More importantly, the K+-controlled G binding/release switch based on C4C5 not only in the solution, but also on the surface, promising for the application for the pesticide controlled release.
